CARL JOHAN JACKSON, OF SUPERIOR, WISCONSIN.

WINDOW.

Application filed July 19, 1923.

To all whom 2'2 may concern:

Be it known that I, CARL J CHAN JACKSON, a citizen of the United States,residing at Superior, in the county of Douglas and State of Wisconsin,have invented certain new and useful Improvements in Windows; and I dodeclare the following to a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in windows of the type in which ascreen is movable simultaneously with one of the sashes to prevententrance of insects while permitting ventilation by opening the sash.

The principal object of the invention is to provide a simple andinexpensive, yet a highlydesirable window construction of the class setforth, of such nature as to effectively rid the house of flies if anyhave entered through other openings.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawings.

Figure 1 is an inner side elevation of a window structure constructed inaccordance with my invention.

Figure 2 is a vertical sectional view on line 22 of Fig. 1.

Figure 3 is a vertical sectional view taken substantially on the planeof line 33 of Fig. 2.

Figure 4 is a detail vertical sectional view similar to the upperportion of Fig. 2 but illustrating the screen in its inoperativeposition.

Figure 5 is a horizontal sectional view as indicated by lines 55 ofFigs. 2 and 3.

Figure 6 is a fragmentary perspective view partly broken away and insection, showing more particularly the construction of the upper sashwhich carries the screen.

Figure 7 is an inside elevation with the upper sash lowered and thescreen in operative position.

Figure 8 is an outer side elevation show ing the appearance of thewindow when both sashes are closed.

Figure 9 is a detail sectional view taken on the line 99 of Fig. 6.

In the accompanying drawings which illustrate the preferred form ofconstruction,

Serial No. 652,564.

the numeral 1. designates an appropriate window frame having a lowersash 2 of ordinary construction, an upper sash 3 of the specialconstruction hereinafter described, and suitable guide strips A for thetwo sashes. The upper end of the frame 1 is provided with a downwardlyopening pocket 5 into which the screened portion of the'upper sash 3, ismovable when the window is closed, as seen in Fig. 4.

The upper sash 3 includes a lower end rail 6 and a pair of vertical siderails 7 rising therefrom, the outer edges of said rails 7, being formedwith longitudinal grooves 8 terminating in the usual openings 9, saidgrooves being adapted to receive sash balance cords 10 which areprovided with the well known sash balances 11, the lowerends of saidcords being anchored in the openings 9, in any desired manner.

Each side rail 7 is formed with a vertical saw-cut 12which extendsthroughout a suitable portion of its length and opens through the upperend of the rail, through the inner edge of this rail, and through. theouter edge thereof, into the groove 8, said out 12,being preferablyflush with the inner side wall of said groove.

A screen 13 formed of ordinary screen ire, preferably galvanized, isstretched between the two side rails 7 and passes outwardly through thesaw-cuts 12, the vertical edges of said screen being bent laterally at14, in the grooves 8, and secured at suitable intervals, as indicated at15. Thus the grooves 8 perform the twofold function of receiving theanchoring means for the edges of the screen 13 and receiving the sashbalancing cords 10.

A relatively narrow upper rail 16 extends between the upper ends of theside rails 7 and is rabbeted into the latter as indicated at 17, so asto be flush with the inner sides of said rails 7. A suitable number ofvertical sash bars 18 extend between the bottom rail 6 and the top rail16 and are cut away at one side of the screen 13, throughout thevertical width of the latter. Throughout the remainder of their lengths,the sash bars 18 co-act with the side rails 7 and the lower end rail 6in securing vertical panes of glass 19 in place, the upper ends of saidpanes being in outwardly spaced overlapping relation with the lower edgeof the screen 13, forming a gap 20 between said screen andpanes, throughwhich flies crawling upwardly upon the panes may escape.

Reducing the upper ends of the sash bars 18 forms an upwardly facingshoulder 21 on each strip, adjacent the outer side of the screen 13, andwhen the sash 8 is raised so that said screen is positioned in thepocket 5 as seen in Fig. 4, these shoulders abut the lower edge of asealing board 22 which is secured to one vertical side of said pocket.The lower edge of this board is provided with a longitudinal channel 23to receive the upwardly projecting upper ends of the panes 19,as'disclosed in Fig. 4:, thus providing a tight seal which will preventthe entrance of cold air. The vertical ends 24 of the sealing board 22are rabbeted to contact slidably with the rabbeted inner edges 25 of thevertical side rails 7, these rails being necessarily rabbeted in thismanner to conveniently secure the panes of glass 19 in place.

In Figs. 7 and 8 I have illustrated the attractive appearance of thewindow both when the upper sash is raised and when it is lowered toposition the screen for use. These views illustrate the fact also, thatthe window may be built into a building without interfering in anymanner with the weather boarding or other external structure, nor withthe plaster or wall board and the interior decorations therefor. Theproportions in Figs. 7 and 8 are not identical with the other views butthey show the general relation of parts and proportions which arepreferably followed in practically carrying out the invention.

By employing the construction above described or a substantialequivalent thereof, a comparatively simple and inexpensive screenedwindow is provided, yet one which will be highly advantageous in allrespects. As excellent results are obtainable from the detailsdisclosed, they may well be followed, but within the scope of theinvention as claimed, minor changes may be made.

I claim:

1. A window structure comprising a frame having a downwardly openingpocket in its upper end, a sealing strip at one side of said pocket,said strip having its ends rabbeted and spaced. from the adjacent sidesof the window frame, upper and lower slidable sashes in said frame, saidupper sash comprising a lower rail, a pair of vertical side railsrabbeted on their inner edges for firm sliding engagement with therabb'eted ends of said sealing strip and having sash cord grooves ontheir outer edges, a vertical saw-cut opening through their upper endsand inner and outer edges, a creen stretched between said vertical siderails and having its edge portions passed through said saw-cuts, bentlaterally and secured in said grooves, and an upper rail to which saidscreen is secured said upper rail having its ends rabbeted into theupper ends of said side rails.

2. An upper window sash comprising lower rail, a pair of vertical siderails hav ing the usual sash cord grooves in the upper portions of theirouter edges, and each having a vertical saw-cut opening through itsupper end, through its outer edge into the sash cord groove, and throughits inner edge, and a screen stretched between said vertical side railsand having its edge portions passed through said saw-cuts, bentlaterally and secured in said grooves, an upper rail to which saidscreen is secured, a vertical sash bar extending between said upper andlower rails and having its upper portion cut away at one side of saidscreen throughout the height f the latter, and transparent panes held bysaid sash bar and said lower and vertical rails, said panes extendingabove the lower edge of the screen in out wardly spaced relation withthe latter.

In testimony whereof I have hereunto aifixed my signature.

CARL JOHAN J ACKSON
